You need to forget about LRU for a moment. The fact that LRU is fundamentally broken doesn't mean that it has anything whatsoever to do with whether we age all pages fairly or whether we prefer some pages over other pages. If LRU is broken we need to fix that, a workaround like your proposal doesn't fix anything in this case. regards, Rik -- The Internet is not a network of computers. It is a network of people.
